the lexus has the toyota red, it kind of looks purple actually



im not going to bother taking the coolant out of the jeep, I figure its been there that long Ill leave it . I have actually changed it three times in 10 years, I did it 2 years ago when I changed the water pump, and I only changed the pump because I had never done it since I owned the truck, before that I changed it because I went to a 3 row radiator from a 2 row.



When your out plowing snow at 4am you dont want a water pump to go bad, I used to change something on the truck every year right before the winter as insurance. I was a little crazy with that thing



the Peak Global is in the vert

rob, dump the dexcool, seriously. It might look good in your radiator when you look at it but it has a serious clogging habit. You dont know how many gaskets we replace on cars with dexcool due to clogged water passages. Seriously dexcool becomes bricks of coolant in the motor and destroy ****, clogs places backing up the pressure or overheating spots which causes the gasket failure.



seriously dexcool is crap, they say 10yrs/100,000 miles, we see degradation of the dexcool at around 36-40k miles...not even the halflife of the coolant. Whenever we leave it as a dexcool system we *awlways* reccommend the customer come back in 3yrs/36,000 miles. Regular **** we say once a year is best but you could probably make it a while before seeing noticable problems.



VW's have horrid coolant systems, tons of plastic necks with millions of senders and **** plugged in to each one. There's this one bitch of a coolant piece on the 2.0 4cyl motors, costs like $175 from the dealer, list price, and i think is 1.7-2hours of labor. Nevermind the countless other problems. VW's coolant is G-12, dealer only item. Decently pricey as well. And its pink.



Oh and never use Stop-Leak in a dexcool system, it turns into like a curdled milk substance.



Least coolant problems i see is with Toyotas, especially if the "Toyota Red Coolant" is maintained in the system, its got an actual lifespan of probably 75-85kmiles and ive NEVER seen any coolant buildups or anything while using that Toyota Red. It looks like KoolAid, always makes me thirsty when i use it .



Prestone is coming out with this new "Do-It-All" coolant. They had it on shelves about 6-8months ago and had to pull it off the shelfs promptly when they found it caused problems with the older VW G-11 Coolant. Now its coming back out, and i think Peak is making one too. Basically it's coolant which can mix with any other coolant and not cause problems.



Oh and if you ever wanna fudge someones motor and coolant system, mix dexcool and regular ethylene-glycol based coolants...once it gets to operating temps a couple times it foams up and the coolant basically explodes.



How long till someone mentions that Evans coolant? wheres banzai.



Also its an LS6, from what I hear we're buying a crate motor and putting it into the car at our shop.



Anyway, cant wait to quit this god damn job, Just got off the phone with my future boss at the port authority starting pay and hours? $32/hour...40 hour week. Overtime available whenever you want it. Of course overtime is time and a half so $48/hour overtime.

Thanks for a nicely informative post. Kind of confirms what I suspected all along about Dexcool. Isn't there some kind of class action lawsuit pending against GM for putting this crap in their engines?

Have i ever seen your jeep? i dont think so. I'm a jeep fan at heart .



Lexus = toyota. it changes color after a little bit, just from heat cycling.
