Title: overheating
Post by: zero32700 on July 10, 2006, 12:46:43 PM
ok so my tgp was overheating about a month ago, been parked taken apart since waiting for a coolant tank that was cracked. got it today, and put everything back together except for the line to the cap of the coolant bottle... where does this line go lol... i feel so dumb.

thanks for your help

edit:: oh i dont know if it matters, but i started the car to make sure it ran and it was still overheating... seemed like the fans werent turning on... dont know if the missing line effected it or not. any other ideas?

the line goes from the coolant bottle cap to the rad cap (under the neck)

Add that line properly, what thermostat do you have? is it working properly?

if your fans are not activating perhaps check your relays (under the hood on the passenger side fuse pannel)

Did you have the radiator cleaned or anything?

I don't think an overflow tank is going to cause it to overheat.  Why you let it just sit to overheat is the next thing I'm confused on?  Why not driving it around and see what happens, the air moving over the radiator does quite a bit.....

It should really have no business at all even being close to overheating, I can run mine down the freeway WITH the A/C on, and its barely above 165....

Oh and turning the heater on does quite a bit on these cars too I noticed.....real fast way to drop temps if idling around town or in traffic :)

thats why I just dumped a bottle of prestone coolant system flush in my new tgp. you never know what kind of rust deposits are lurking in there clogging up stuff. if you do one, make sure you follow directions on the bottle really well and just stick a hose in the top of the rad., dont use the prestone T-fitting or flushing system with the hose attachment. those are total garbage.

Actually you are backwards Dave.

From the nipple on the bottom of the TGP/TSTE reservoir it goes to the rad cap nipple. Nipple to nipple. The cap tube is nothing more than a piss tube to direct the boil over to the ground.

You will want to check two things real easy for overheat. First make sure your rad cap is not defective. I had one along time ago swell at the rad cap seal. It was hanging up of the fill neck and allowing the pressure to escape allowing it to overheat. Next you want to replace your t-stat. T-stats normally fail open...but yours may be hanging up and stuck closed. When you replace your t-stat make sure you bleed the system. If you do not you are pretty well guaranteed to cause engine overheat and failure.

If you run anything through your system to "clean" it out be ready to possibly replace your radiator. It is 16 or 17 years old and the possibility is VERY high for you to loosen too much up and show leaks. My TSTE did that to me and it has less than 100k miles on it.

car shouldnt overheat sitting there, mine sits at less than 200 degrees on a 100 degree day idling with the a/c on

yes, i figured he had it backwords.
i drove the car down the street tonight and it didnt overheat, but it was higher than it was when i first got it. i will get a new cap tommorow and see how it does.
i did bleed it after doing all the work to it, a little air came out but i will keep checking it.

on the good side i threw  a k&n filter on the turbo, and i love it, dunno if it makes any differance cause i wasnt really driving it but i can really hear the turbo now... i like.

There still must be something not right if its running that hot?

Oh and enjoy the cone right on the turbo, hopefully it doesn't melt.  My got all deformed and bent so i gave up the really loud turbo noise for moving it down where it can get colder air....less heat soaked too
