Solution to H2 overheating problems
2 Attachment(s)
I live in Ecuador, and often drive up the Andes mountains to heights of 14,000ft as well as driving an hour and a half to the beach at 90mph in temperatures of 90-100 Fahrenheit. My H2 has a Vortech Supercharger, I have taken out the catalytic converters for even more power (makes a BIG difference), and I have installed four HID spots in front of the radiator grille. So if anyone should have overheating problems, it is me!
Before making the changes detailed below, I observed that when pushing the car hard the water temperature would rise above 210 to 230/240, and only went back down to 210 when I lifted the foot off the accelerator. The transmission oil temperature would also rise to 230/240 and remain there, even after lifting the foot off the accelerator. I have always used synthetic transmission fluid (Mercon 5), so I hoped that no permanent damage would be done to the transmission. After reading innumerable comments on the Elcova web site, I did the following:
I attach a photo of the installed transmission radiator and another of the new pan and exhaust heat shield. |

Re: Solution to H2 overheating problems
Michael have You installed the 160 degree engine thermostat? This would be a very good upgrade. Can be done in 10 minutes and can get it from LIG as You did You gauge set.

Is there any reprogramming that needs to be done to the computer when if you switch from the stock temperature thermostat? I swapped out one in another vehicle and because of the change I throw everything out of whack. The engine started running to rich and stalling out. I had gone from a 185 degree thermo to a 135 thermo. Once I switched back to the 185 thermo all the problems were fixed. Just curious if this was a problem with the H2?? |
Re: Solution to H2 overheating problems
MB, where did you get the heatshield from?

Re: Solution to H2 overheating problems
Heat shield was obtained from Summit Racing:

Re: Solution to H2 overheating problems
Michael, not to change the subject but in the picture I can see your hood cable with the rubber tube or "coating" on it. Those tend to hold in the moisture thereby corroding the cable causing it to break. Can be kind of a scaring moment...The new replacement cables don't have the rubber on them.

Mine were literally "white powder" inside after they broke.

Re: Solution to H2 overheating problems
Where online could I get the new straps from?

Re: Solution to H2 overheating problems
As Phil can attest, mine are still in good shape because I spray mine with some anti-rust lubricant I use for everything.

Sorry for late reply. Holidays really messed up time. I would only lower the thermostat temp if I was in a normal condition with engine temp. and went to programmer that would in turn allow Me to run cooler thermo by telling computer you were doing so. Of course at same time getting the benefits of other options of programmer. The only other way I would run cooler T-stat with stock tune is if You are in a hot temp part of the world and needed the cooler T-stat to try and get to a cooler engine temp and maintain a stock engine temp.
