What did the coolant in there look like?

People are offering you advice and you're just doing your own thing. Stop beating on your car to solve the problem and actually try to fix it m8.

1. Add coolant and be sure that your coolant is good. You've done this. That's only STEP 1 in diagnosing.

2. Check your oil level and see if there's coolant present. Coolant in the oil typically looks like a whitish paste. If this is the case, there is a leak internally somewhere. Most likely, your head gasket.

3. You need to do a pressure test on the system while its cool. to be sure you don't have an externally visible coolant leak somewhere. If you find a leak, you need to fix it (obviously). You should also be checking to be certain the cap on the radiator is sealing properly. There will typically be yellow gunk around it if its been leaking. Same with the oil cap.

4. Check to see if your thermostat is functioning. Some people can do this on the vehicle by squeezing the coolant hose, and waiting until the thermostat opens. When this happens, you can feel the pressure in the hose change. My personal recommendation is to put it into a pot of water and set it to boil. If its functioning, it will pop open right around boiling temperature. If it doesn't open... it isn't functioning.

5. Inspect the belts and the water pump. Does your water pump have any shaft play? Is the belt installed properly, or failing somehow? You can also manually turn the water pump to be sure its actually movable.

6. Is there any type of blockage to the cooling system? Is your radiator fan spinning, and turning on and off as necessary? Is your A/C installed and does it work? Is it on when you're doing this?

If you're ONLY noticing overheating at high engine loads, I would suspect it isn't a fan related issue.

I've had similar issues in the past with another vehicle, fine normal, but under full load would ge hot. was the headgasket and it was spitting coolant too as the cooling system filled with exhaust gases.

+1 for headgasket unfortunately.

The leaks may not show unless under pressure. Just an fyi.

due to the weather and me having to go to work today, i decided im going to have to take a ride to AWDmotorsports tomorrow, i'll see what they say. im sure it probably is the headgasket. so i prefer having the people with the right skills do this job. i appreciate everyones help {thumbup}

Take it easy on tomorrow's trip. If the head gasket is the culprit then what is happening is air is being pushed into the water jacket. This also means that coolant gets pushed to the jug - and, when full, onto the ground. So, things could go from bad to worse pretty fast.

will do, good thing AWD is only about 20 or so miles away from me. plus as i said the car runs perfectly whikle driving normal ,so i would think i should have no problem. {thumbup}

Keep us posted on what this is/was so we can hone our interwebz diagnostic skills :lol:

donmeca2020 Oct 17, 2011 07:44 AM

well , i of course called ahead this morning before i left to go up on that 20 plus mile drive to AWD, it appears they arent open today or maybe they just open late..... if i dont hear anything back from them shortly then i'll just go to work like normal and try again tomorrow. sucks because i was looking forward to geting the car fixed today... oh well, what can you do

BigT Oct 17, 2011 08:25 AM

Same thing was happening to me. I changed my thermostat and all was well.

lol what? Did you have an appointment? :lol:

Head gasket is a possibility but usually you will "push coolant" into the over flow tank, so it's usually full when you check it.

like i said i hope its not that

donmeca2020 Oct 19, 2011 06:37 AM

well after dropping her off to AWD yesterday morning, i patiently was waiting all day to get the call to come pick up her. i ended up getting a call from shawn at around 5:30 - 6ish. he told me they were doing diagnostics to my car all day and they came to the conclusion that it is more then likely my HEAD GASKET......

So i had to end up leaving my blue beast at AWD overnight, but since my car is there not only will i be getting the head gasket fixed, im also having them throw in some ARP head studs, and take my old exhaust set up off and install a Greddy Ti and downpipe that i had sitting in my house for the last few months !!!
