The next step would be to verify the automatic cooling fan is coming on and functions when the temp rises in the engine. You may also want to check or have someone check the radiator's flow, it may be clogged.

Replaced thermostat and new coolant on 2004 suzuki forenza due to overheating problems doing driving on freeway or street as soon as i leave home. Problem stop one day then the next day i had some rough...


there are only 2 ways to overheat,
and vast causes !
1: engine making too much heat.
a: eg. cam/spark timiing way off. eg retarded timing does that.
2: Cooling system failure.

just 2. finding out which one takes tests.
I do my engine checks first.
A; compression. ok
b; timing right.
C: egr closing,
d: cat not melted closed down (huge backpressure, "guaged"

then when happy my engines happy,
I then attack the cooling system.
Thermostat new, and not put in wrong,
wax side to input side,RTM, bleed hole high (jiggle pin,etc)
I use an IR pyro gun $15 to check ALL rad tubes top and bottom
so see if one or more is clogged,, this is easy, ask.

does it over heat parked at a read light
does it never fail moving fast.
these are the top clues.
only fails A/C on?
fans all work, some have 3 on A/C cars up front.

the question is, , is the stalling caused by overheating or is only a victim. only you know that, as you are driving.
if you see bad running before the oveheat, then its just that.
is the car pinging?
engines that ping overheat and blow pistons.
engines that overheat can ping.
but in the latter, it overheats FIRST.
see?

I have a 2004 volkswagen jetta1.8 turbo . I replaced the 2 water pumps, and when i have the car in park after a couple of minutes it starts to overheat what might the problem be?


Make sure the fan is working. When it starts to overheat, the fans should be on. Fan failure is common. It could also be the thermostat, which is located under a black plastic piece on the bottom front of the engine. The thermostat is easier to replace, 2 10mm bolts.

My 2004 Dodge truck 4.7L over heats when I pull my trailer. I replaced the thermostat and the water pump. What do you suggest. Should I replace the rad cap? Trailer weight is 1500lbs.


Seeing as it seems you do not have any overheating problem other than when you are towing I believe that you need to make sure that when towing you do not have the transmission in overdrive unless going downhill. This is the #1 reason for transmissions failure while towing. Trans overheat = engine overheat
Hope this helps.

How to tell if water pump for 04 cadillac srx needs to be replaced.


Your car will overheat very fast and you may either notice coolant leaking from the location of the pump and also possibly a squealing noise due to a bad bearing. Overheating can also be caused by a bad thermostat.

Even after replacing the radiator, thermostat and


The problem with overheat is due to poor coolant circulating. The main culprit is the Radiator. When the radiator is clogging up, coolant can't be circulating. The stagnant coolant inside the engine water jacket keeps absorb heat from combustion chambers having no way to dissipate the heat then the engine is overheated. You can test the water pump by removing the thermostat, then hooking everything back. Open the radiator cap, then turn on the engine to see if water flowing down to several small tubes inside the radiator. If water can't go down fast enough to cause over flow at radiator opening then your 90 Legend Radiator already got clogged up. Replace with a new radiator, not even a rebuilt one. Good luck.
