K2500 suburban Thanks for your reply about my problem with engine temp. Water pump was replaced 2 months ago when they also flushed system and replaced thermostats, this is when problem started, found last week that they had fitted thermostats wrong way around so turned them around and replaced coolant and coolant bottle cap but still have the same problem

If your going to fix this problem yourself, remember to take care when dealing with hot engine coolant.
If your problems only started once the cooling system was drained for repairs, it sounds like there is just trapped air in the block that needs to be bled out. At work I have a tool made by Lisle tools, which is actually a funnel that attaches to the radiator. I've had great success with this tool to fill and bleed cooling systems after repairs are made. I purchased this tool from my Snap-on dealer, but you may be able to find one elsewhere.

I hope this helps.

Hmm..ty ..well let us go backwards a little then..why did you replace the water pump and did your motor overheat?... could we need to do a compression test and be sure you did not hurt the top end of motor.. ie head gaskets etc..?..let me know

    so we can assume circulation is still the problem...turn on/off heater and tell me if there is any change ...another area we will look at is the fan clutch, it should be close to locked when cold and should be making quite a windy racket til she warms up...hear that..or observe the extra air flow when first running motor?

Why does the temperature gauge on my 1995 Chevy K2500, 5.7L read 150 degrees ?


If you replaced the SENSOR and not the gauge SENDER, there's your answer.

The SENSOR sends the computer (ECM, PCM, ECU, etc.) the engine temp so it can make the adjustments to the fuel, timing etc.

The gauge SENDER makes the gauge read what temperature the engine coolant is.

Hope the helps.

Replaced radiator and tstat still over heating, water pump a little over a month old


my used 4 cyl jeep radiator would only drain 1/2 of the fluid. jumped up and down on bumper and this dislodged the sludge in radiator and/or engine. flushed twice, then now notice low temp reading on gauge (out of specs) due to a low temp thermostat that someone installed due to previous over heating (sludge). Replace with factor spec thermostat and everything is fine.

Why is my 2002 Taurus over heating


I would say water pump is out again. The pumps are common prob. I would suggest getting lifetime warranty one new if possible. Could try leaving climate control on ac mode or defrost since this makes fans run more continuously and if that helps then replace pump.

My 2005 dodge neon sxt has been running hot for a few days.. 2 months ago i got it repaired for this same problem.. what can be the cause of it to continute to run hot?


Here are the least expensive items in order of least to greater...Check for proper coolant level in small tank next to the radiator. If low... refill to proper level. make sur eyou use the right stuff for you particular engine . Any good auto parts place can help with the "right stuff"
if OK, next...
Replace the radiator cap. if still getting hot, replace the temp sensing valve ( thermostat) at the engine side of the top radiator hose. If it looks grungy, you may still need to get the whole system flushed.

This is a very messy job that removes the foul stuff in the cooling system which may prevent coolant circulation.
If the water pump is defective and it was changed 2 months ago take it back to the place that installed it.
Check for loose belt driving the water pump first
