87TC is getting hot while idling

I'm not sure what's going on, I recently installed a aftermaket boost gauge and A/F ratio gauge and the car runs almost into red while at idle and cools down when driven SOMETIMES. It always seems to get hot while sitting still but gradually cools down when driven, even before the gauges were in. I'm not sure if my stock gauge is fooling me or if maybe I need a new thermostat. No fluids leaking, oil is normal, coolant full...Any suggestions?

1. Check fuel pressure (35-42 PSI with ref line off)

2. Check timing (10* with spout out)

3. Make sure the coolant level and %age is correct (50%-50% or 60%-40%)

4. Install a new thermostat (192* or 185*)

5. Make sure that there are no obstructions (like card board from the winter) in the radiator or infront of the radiator (may have to have it flushed or rodded out)

6. Make sure that the air dam is still intact and not broken under the front bumper (if it is not there then while on the highway there won't be enough air flow through the radiator to cool it off...make sure that it is solid and most or all of the bolts are in place)

I am sure that some of the other members will come in and say more, this is all that I can think of right at the moment.

Does the oil and fuel gauge read on the high side as well? Yes, the stock temperature gauge system is known for being inaccurate and having problems. But it would be wise to not dismiss the concern.

Is the passenger side fan cycling off and on as it should?

The oil preassure always seems at 3/4 or above, the speedo is reading about 7-10MPH fast and the fuel gauge seems right on.

Does anyone know where to get or have a custom panel for aftermarket gauges for 87TC, so I can void all of the factory gauges (including speedo tach, and all others? Or is this too big of pain to replace them all?

Also, is there any way to tell if it's truley getting hot, besides letting it overheat and possibly blowing the head gasket?

Get a scanner and plug it in and see what temperature the computer says it is. You could also check to see if your car is throwing any codes like for the coolant sensor.

Cant do that. Only OBDII has the ability to read sensor outputs via a scanner.

Joe Cool (Joe F.) made a BEAUTIFUL custom gauge panel filled with all Autometer gauges. I think it cost him about $400 or so, plus a lot of time doing fabrication.

Do the cooling fans come on?
There is an article on diagnosisng fan problems in the FAQs.

I will perform the fan test as soon as I get home. I saw a way to run a manual fan switch for other years in the FAQ. Is there a way to run a manual fan switch for the 87-88TC's?

Thanks for all the input!
