So i seafoamed my car(thank you for diy) and my car is hella faster now. But now for some odd reason when idleing the car temperature gauge goes up but when i shift into gear and step on it tempeture cools down????? so does anyone know what can be the problem, the car is a 2000 acura tl-p

 

check the colant level in the res tank and make sure the rubber hose is connected inside to the res cap
check coolant level in rad when COLD
whats your current miles? water pump done if over 100?

 

are you shifting to N at stoplights?

 

well it was low today (the coolant so i added some than it started acting wierd) but i have 92 k miles

 

yes thats how i suppose to cool it down cause 3-4 more bars and it would be at max hotness

 

Thermostat stuck shut?

 

it cools down when you drive cause the belts make the water pump move faster thus moving more fluid through the motor. If you car ever heats just put it in the lower gear you can to keep the water pump moving the fluid as fast as possible through the system.

 

so what do you guys think is the prob?

 

Very possible. I would check this first. It's a cheap part if it is bad.

 

I think it could be your thermostat stuck shut. I am thinking that when you give it some gas, it opens it up and lets the hot coolant circulate.

 

could it be from seafoam cause first time its happened. is there a diy or can someone explain how to fix it? Thanks

 

does the radiator fan turn on. try sitting still wait till it gets hot then turn on the a/c. it has a seperate fan.. if the temp goes down then your primairy fan isnt turning on.

if it gets cooler while your driving its cause air is cooling the radiator. and sitting still your fan is supposed to do that.

 

seafoam had nothing to do with your problem

3-4 lines of temp means a major issue and should NOT be driven until fixed
First most likely is thermostat- movement causing airflow lowers temp
BUT thats a lot of needle movement!!

Or water pump is failing- with low colant level thats my first thing to check- where is it losing coolant from? nothing matters until thats resolved
Check under the wp for coolant leak from a small weep hole cast into pump body
Ck rad cap seal for leakage
pressure test cooling system

 

the driver side fan is radiator temp controlled by a sensor to turn it on, common part failure- the sensor

the passenger side is hooked to ac operation and in high engine temps

 

The seafoaming had nothing to do with it.

Here is a question, What vac lines did you use. Did you take any thing off of the TB and possibly get them mixed up because there are coolant lines on the TB.

 

well now the car is doing just fine i did some driving around on it. so now it doesnt go above half way mark. I dont know what could have caused the problem

 

i dont even have one

 

sounds more and more like dieing thermostat- gave you a few warning sticks...-
then operates fine for a while until suddenly- the temp shoots to redline and you lost the engine
