Engine Ice Question...

I bought soem engine ice today, and when I got it home and started looking I noticed it has alot of white particles in it ? It doesnt look normal ??? any input would be nice....


Not Hardly!

So is his engine ice OK or did he get a bad bottle?

Well I called Cycle logic and they said it was normal... they said it was the anti-bonding agents in the coolant... and I wasnt the only one to ever call or notice... :) well hope they are right...

All you have to do is shake it up!! The little white particles will go away! The stuff works great.

I've tried Water Wetter and I will be switching to Engine Ice. The Water Wetter was a waste of money.

Geeze, I guess I just bought some Engine Ice and didn't even know it! Engine Ice and Silkonene coolant contain the same ingredients: propylene glycol/water mix. Ethelyne glycol is the standard toxic stuff that comes in most bikes. Proylene glycol is basically non-toxic. I just put the Silkolene in my CRF and added the coolant tank in frame mod. I'm off to Left-Hand canyon this saturday for the "acid test" of boil-overs. Very steep, very slow, technical climbing that has boiled every water cooled bike I have ever owned, including my DRZ and KTM250EX/C. If you want to know why CRF's are prone to over-heating, just look at the radiator closely; The thickness of the core is 1/2 normal size, then the cooling tubes are also thinner. With any luck Honda will make a CRF450X with larger capacity radiator than can be retro-fitted to the CRF. Unitl then, it looks like coolant recovery tanks and engine ice.

I'm going to grab some on the way home tonight. Is one (half gallon) bottle enough for the CRF?

I don't have my manual handy here to look up how much the bike takes.

Actually, It's the "anti-foam" and "anti-corrosion" properties.

It's in all coolant/antifreeze products, but because Engine Ice is in a clear bottle...you see it.

It's normal.

Even though Silkolene's product is a PG-based product, it isn't the same.

Engine Ice does have additional additives and is pre-diluted with a more clean, more pure water (Deionized).

There's a difference.

For all you folks happy with the product, EXCELLENT!

and Thank you.


and Yes, one bottle is enough

Last Question:

I'll drain all of the coolant out of both radiators, but don't think I can suck it all out of the engine.

Is there any problem mixing what's left in the block with the Engine Ice I put in the radiators?

Not really

But you should at least run some clear water through it.

As for flushing the system, we recommend a very simple and cheap radiator flush.

Go to your local grocery store and buy "White Distilled Vinegar" and mix that 50/50 with some distilled water.

Fill the system with the 50/50 mix, run the bike until warm, let cool, drain and then run clear water through to wash out the vinegar.

It's the same idea as cleaning your coffee maker.

The vinegar is acidic enough to remove any scale or impurities, but not so harsh that it will harm your delicate seals and gaskets.


Just a note...Ice and ProKool are AMA legal in the Pro classes.


That "additional ingredient" that you say Silkolene Pro-Cool doesn't have wouldn't happen to be pRoFiT would it? :)

Do you have any measurement info on heat-tranfer properties to back up why I should buy Engine Ice over Pro-Cool?

(just a question, not a flame!)

Another question for Engine Ice guy...does Engine Ice have a shelf life and if so how long can you store it. Might want to buy a few and keep some on the shelf. Thanks JP

This stuff seems to work quite well. I've been running it about a year and have ridden all over the place from wet and cold to hot southern CA. After doing the frame overflow tank, I never seemed to have to worry about losing the fluid. Engine Ice seemed to keep the bike from overheating like before, but you just don't notice it anyway when you are not spitting fluid all over the place.

Hi Dave

I bought engine ice just because the guy that posts here is really cool (no pun intended). I needed coolant anyway.

I used it in my own YZ 250 as well as th eneighbor kids CR 80. Both bikes stopped puking out the overflow while idiling. I am not sure what that means, but I will continue to use it. I think it is worth the money.

It is not as if they give away the automotive stuff anyway!

      Jeremy Martin Leads the Charge for Wiseco Riders at Daytona Supercross
      Christian Craig Turns in Career Best in 450 Competition
      MENTOR, Ohio (March 13, 2018) – Jeremy Martin showed the way for Wiseco-sponsored riders in Saturday night’s Monster Energy Daytona Supercross presented by Honda. In a season marred by bad luck and misfortune, Martin put together a near flawless ride to earn his first Eastern Regional 250SX Class podium finish of the season.
      Martin qualified eighth for the division’s annual visit to the World Center of Racing, finished fourth in his heat race, and came home second in the 250SX main event, missing his first win of the year by less than a second.

      “It’s Daytona, a real man’s track.” said Martin who sits fourth in points. “It was the toughest race of the year as far as fitness. I had to slow down a little bit, halfway through the main. I was getting close to (race winner) Jordon (Smith) and I was starting to think about where I could make a move on him, then I made some mistakes and he got away from me. Couldn’t quite get close again, but it’s good. We’re on the podium and in contention for wins again. That’s something I haven’t been able to say in supercross in a while. We want to get wins and now we know it’s coming.”
      Martin’s podium was a bright spot, but the rest of the event was rough for the GEICO Honda/Factory Connection squad. RJ Hampshire crashed hard in his heat race and had to be transported to a local hospital. He injured his back and ribs, but shoulder pain left him with the most concern.
      “I felt good on the bike all day,” said Hampshire via his Instagram account. “Had some pretty good speed and my foot just slid off hitting my shifter in those rollers during that heat race. After seeing the pictures from the crash I’m very thankful I didn’t take a shot to my head. I have some fractures in my T3/T4 in my back and ribs. Also have some damage to my lungs which is why I’ll be spending a couple nights in the hospital. I’ll be getting some more checkups this week on the shoulder also.”
      Cameron McAdoo, the third member of the team, was unable to compete at Daytona after being sidelined with a hand injury two races ago in Atlanta.
      Across the paddock, in the premier 450SX Class, Christian Craig got the call to fill in for Team Honda HRC. With the team’s regular riders Ken Roczen and Cole Seely out with injuries, it was up to Craig to carry the load for the factory team, and the upstart rider didn’t disappoint.
      The San Diego native was solid in both qualifying sessions, won his heat race and snagged the holeshot in the division’s main event. After relinquishing the lead to eventual winner Justin Brayton, Craig continued to show he was up for the challenge. The 26-year-old rider raced for second and third for most of the 20-minute-plus-one-lap feature before losing one more spot in the late goings to bring his No. 32 Honda CRF450R home fourth in the final rundown.

      “I had a great week testing with the team,” commented Craig. “They came down to Florida right after Atlanta and I feel like we really improved. Just getting more time on the bike and getting more comfortable was huge. I started off race day feeling really good. My qualifying position didn’t really show it, but overall I was happy with my riding. It’s all about having fun out there, and man, that’s what I did tonight. I was up front in the heat race, fell to third, but then the two guys in front took each other out so I ended up winning. You can call it luck or whatever, but I just put myself in a good position to capitalize on people’s mistakes."
      “I had a good gate pick and some confidence going into the main. I grabbed the holeshot and led for almost the first lap, but [Justin] Brayton got by me pretty quick. I stayed second for quite a while. I just rode my hardest and did my best. Unfortunately, a couple guys got by me so I ended up fourth. The track was so tough. This is only my second time racing Daytona and last year didn’t go well, so I really wanted to get some revenge this year. It’s better than the week before, but man, I was so close to a podium. I just need to keep putting myself in good positions and work on getting better each weekend.”
      Monster Energy AMA Supercross rolls on this weekend when the series visits the “Gateway to the West” for its annual race at the Dome at America’s Center in St. Louis. The 11th of 17 races on the 2018 supercross calendar will be televised live on FS1 Saturday, March 17, beginning at 8 p.m. Eastern Daylight Time, 5 p.m. Pacific.

      I have a 03 450 that I just got and it runs great! I love my bike and am big on preventative maintenance. I have searched the threads on TT and have not found any descriptive threads on how to check valve clearance or adjust them. Just by looking at them, I can see that the intakes need to be shimmed and the exhaust valves can be adjusted quite easily unless one needs to be adjusted differently than the other.
      I tried to do it last night, and lined up the marks on each side to get the piston to TDC to check adjustments and could not get any readings on tolerances on either the intake nor the exhaust. I moved the crank a little bit forward and got a .011 reading on the exhaust valves. I read in a thread that the spec was .011" for the left one and .014" in the right for the auto decompressor. The spec I am using for the intakes is .006" Are these specs correct? :excuseme:The only issue is that the adjustment for the exhaust valves is one and the same. Different from my KTM where you can adjust each valve individually.
      No matter where the cam was on the intake valves, I could not get any readings. Does anyone have a thread, website, downloadable manual, or article on checking and adjusting valves in these beasts?

      I recently replaced water pump and seal after I noticed that my '02 CRF450R was spilling coolant on easy trail rides. After the water pump swap (which was successful), I noticed the same problem. It's interesting - the bike only spits coolant (I mean a LOT of coolant) after passing anything above 1/2 throttle. The bike makes this weird 'gurgling' noise, like trying to suck through a straw when your glass is almost empty. This is weird because I properly bled/ burped the radiators with coolant, and filled them to normal operating levels. The coolant spills through overflow hose. 
      anyways - I swapped the radiator because I thought maybe the bike was running hot. I purchased oversized radiators, bought a 1.6 radiator cap (with a temp gauge) and bought engine ice. The bike runs very very cool - the temp gauge allows me to see this. Still, the bike shoots coolant out of the overflow after going above half throttle, making the same weird gurgling noise when it does. Bike has all of its power, top end was replaced not too long ago. 
      I'm lost and don't know what is wrong with the cooling system in my bike. How do I make the bike stop shooting out coolant, and stop making the weird gurgle noise??? Any advice would help me!!! Thank you!

      I have a brand new Barnett Extra plate setup still in the box. It replaces the judder spring with a regular fiber. My old clutch had a judder spring break which wiped out the stock clutch. I was in a bind ordered this kit but it ended up coming 2 days later then it was suppose too. So now I don’t need it asking $180 SHIPPED 
      —“Complete Extra Plate Kit- consists of 8 Kevlar friction plates, 7 tempered steel plates and a set of springs. Provides maximum clutch capacity.”—
