Question about 1997 Oldsmobile 88

1 Answer

Radiator Flush without emptying the radiator

My 1997 Olds 88 has been running hot, the needle goes into the red zone on the indicator and there's a small puddle on the passenger side wherever I park that smells like radiator fluid. Someone I work with said it's probably clogged up near the heater core. Any help/diagrams would be appreciated.

I doubt it. If the heater core is plugged up the cooling system still functions but you don't get any heat.
The radiator could be clogged up, or it could be a sticking thermostat among other things.

SOURCE: Heater Core

My mechanic tells me it is almost impossible to get to it without
taking out the dash. This will give you the clearance you need
to replace it. You might try it from under the dash if you have a
good back but i don.t think there's enough clearance to get it out.
I bought a salvage 1997 lss Olds and the airbag popped the dash
so we had to replace it. Not an easy task unless you've done it

SOURCE: Had radiator flush. Even before this was done,

A few things to consider when diagnosing poor heater

  • Flushing the radiator doesn't do much in terms of heat. The heater core should be flushed to get rid of anything accumulated in there over the years.
  • How hot is the engine actually getting? If the thermostat is stuck open the engine may never reach proper operating temperature.
  • With the engine at operating temperature feel the hoses going into the heater core, are they hot? Some vehicles use a heater control valve that only flows coolant through the heater core when activated. They work off of vacuum and it isn't uncommon to find a broken vacuum line at the valve.
  • Are the doors in the heater box operating correctly? Can you hear the heater door inside the dash open when you select heat?
I hope this helps in getting your heat to work for the upcoming season.

Why is my 1997 olds delta 3.8 l running hot almost in the red?

Check if the radiator fan comes on when temp is about 50% of the gauge. Check if there is temp difference between top radiator hose and bottom one. Get the coolant thermostat checked. It gets stuck and will stop hot coolant in engine from flowing to radiator for cooling.

1996 jeep cherokee temp gauge reads hot 10 mins. after start-up

If you have a viscous fan hub then have it replaced as it is not drawing air through the radiator at idle or slow speed (crawling traffic). Check that are no air locks in the system as they will cause heating problems.

Driving with air on gauge goes up and runs hot to red line. flip to heat gauge goes down. start car up after sitting for hours,let idel for 1hour with air on ok,start to drive with air on gauge goes up and...

Did you flush the radiator when you replaced thermostat too? Sounds like it's clogged and the coolant is not circulating as it should. It probably needs to be rodded out or replaced by now.
Check your cooling fans for proper operation. Make sure the outside of the radiator & condensor are clean, and not full of bugs & debris...I hope this helps.

I have a 1997 Honda Accord ex that's running hot only when the ac is on. When im parked and have the ac on it doesn't run hot until i start driving for about 20 mins or so. Both fans are coming on...

Thanks for choosing FixYa and welcome to the site. The fans should come on as soon as you turn the a/c on. There shouldn't be any delay. You could have a bad water pump, valve, or impeller. A bad head gasket can cause overheating also, but I would look into the pump first. Do the flush first. It may help. If it doesn't, look at the water pump.

Heat gauge goes up to red, water, anitfreeze and poil all right. only goes up to top when heater is not running

When the heater is running you increase the flow of hot water providing more opportunity for it to cool down. You may have a blockage in one of the hoses or in the radiator core. A radiator flush may take care of the problem. Try the flush before proceeding with anything more costly.

I have a 1996 Mazda 626 2.0 Automatic. It runs

of course the top is hot water goes into the rad from the top and out of the bottom into the engine, the fact that the belt broke makes me wonder about the integrity of the water pump, the impeller might be slipping, could still be the rad , does the heat go from the top to the bottom???

Where is the petcock located on a 1999 oldsmobile

Most are difficult to get to and so many don't work correctly that it it's almost silly to even use it. Far easier is to simply remove lower hose from radiator. It works better and faster. Just be careful though...Don't do hot or you may get an unwanted scalding bath!!
