#16 of 156 Water Pump Belt
Aug 26, 2008 (8:00 am)
Hello all, sn5bah here, maybe one of you can help me with this one. My 2000 Mercury Cougar gauge shows that it is overheating, the thermostat has been removed and the whole system flushed. New water pump installed. Water pump belt broke off yesterday. Is this hard to replace, payed a mechanic to replace the water pump, but this time I want to do it myself. Need a quick response, this is my only vehicle.

V6?Could be IMRC control unit faulty.This device controls the opening of the valves at approx. 4000rpm to allow max power!

did you ever get a proper diagnosis for your problem?
Was it in fact the IMRC???

Long time no chat. So it seems recently my gauges started going the full distance from 0 to 160 upon startup. Is this new? Has the cougar always done that? I don't think it has. All of my gauges go the full distance. Does your cougar do this? Is it possible that it has always done this, and I haven't noticed in 7 years?
That and tonight the cougar didn't start. It just clicks. I'm thinking the battery is low, though the highlights are bright and the internal stereo, lights and etc are fine. I've been warned a couple of times that the battery is low. I think that will be the first thing I change.
What do you guys think about my gauges.. am I just stupid?

Need help with my cougar. Temp guage shows hot. I have replaced the coolant temp sensor three times Bought two new ones and tried one from a junk yard. One of the new ones did not mark at all on the gauge. The one from the junk yard and the other new one mark hot. I have installed a new water pump, replaced all of the belts, replaced the radiator. Put a new radiator cap, had the whole system pressure tested. All checks out to be good. Pressure holds up, no leaks anywhere. What can I check to fix this problem? Any and all help will be greatly appreciated.

Have you measured the actual temp of the coolant (to determine if the gauges/sensors are wrong)? An IR temp sensor is useful. Even the temp of the readiator metal or coolant hoses will give a good approximation.
How soon do the gauges show "hot"? If soon after startup, your coolant thermostat is stuck and won't open. In this case, one of the rubber hoses is hot, while the radiator is still cold.

If I am on the highway doing 70 mph, it takes about 10 mins. for the gauge to start marking hot. Have had it checked with an IR temp sensor, have checked the hoses to see if any are collapsed and none are. Water in the bottle, does not boil out. Thermostat is brand new.

I'd say: if not done already, change the coolant termostat ($6.99 at Autozone), install a lower temp than factory (180 deg F or less). Its not that much work and costs nothing.
Are your fans kicking in?
