Hi All You Rammers Out There...!

A quick question about coolants. I drive a 2003 4.7L 1500 and I want to flush out the cooling system and add some fresh fluid. The Haynes Repair Manual for this truck is unequivocal about coolant, saying that it must be Morpar 5-year/100,000 mile "or equivalent". Anyone out there have any idea what is an acceptable "equivalent" that could be less expensive than Morpar? I'm overseas, and Morpar is pretty expensive over here. Thanks for any suggestions. Cheers.

 

Zerex G-05 from Napa. I just did my 3.7 a couple weeks ago, make sure to pick up some distilled water, unless you buy the premixed stuff.

 

Bakerman,
I'm not familiar with the Ukraine. However, I spend part of my year in the Philippines where I have a couple of motorcycles and a Nissan van. I'm sure the Ukraine can't possibly be as difficult as the PI to find quality automotive products. As for coolant use either the Mopar recommended coolant or a major name coolant that is compatible with your vehicle. I always use coolant that is clearly marked as an alumimium compatible coolant for my bikes and van just to play everything safe. I have found often when I ask a sales person a question, they will tell me exactly what I want to hear. So check everything yourself before pouring it into your ride. Overseas living certainly has its challenges. Good luck...

 

Ah, I didn't realize he was in the Ukraine, I guess you might have to order Zerex or mopar coolant if you want it to meet Dodge/chrysler specs. You could just do a good flush and switch to a different coolant that is readily available like RedTruck recommended.

 

That's just a Synthetic coolant is all. Normal green stuff is good for 30kmi. The Synthetic is good for 100kmi plus has additives to help keep contaminants from eating up aluminum blocks/heads. That's the main reason for using the stuff plus maintenance intervals are longer too.

If you can get Dexcool, just go with that stuff. It's Synthetic coolant for GM cars/trucks. Same sh*t just a different color/label.
Make sure you colpetely flush the engine out with a garden hose and try and use distilled water if you can. It helps out alot. Distilled water can easily be made by filling up a 5gal pail and letting it sit for a few days or you can boil it. this removes all the bad stuff that eats rasiators, aluminum and other soft metals that the Synthetic fluid id suppose to help battle against.

 

Thanks, man.

 

Very helpful! Thanks for the advice!

 

DO NOT PUT DEXCOOL IN YOUR TRUCK!!!

There have been numerous class action suites against it! It is the single most corrosive thing you could possibly put in your engine short of acid!!!
Read the above link, or Google it. From what I understand, GM is well aware of the problems, but lacks the funds to overhaul the product at this time.


Go with any good name brand coolant that specifically states that it is safe for aluminum engines.

 

I didn't know that! I'v had DEXCOOL in my truck for a while now. Haven't had any problems.... yet? HHHMMM maybe time for a flush?

 

hmm. my coolants a little low. should i just go ahead and top it off with some from vatozone or flush it?


also dumb question, but when checking the trans fluid you want to have the truck on ?
