Just blew the debris out of the condensor and radiator, good lord, looks like something blew up. Sure hope brings my temperture down, been reaching upwards of 240 @ idle with outside temp of about 70 degrees.

 

Bill check your thermostat. It maybe almost closed

 

Found another problem, electric fan not running. Any idea where the fan relay is on 89?

 

yep, just did my own, except I removed the radiator, and condensor both!

I bought the car in Augest for my wife (128K miles) she complained that the car was running hot while she drove it home, so I let it idle in the drive way while both fans were on high, the anolog gauge (didn't know about the digital) hit just below the hash mark .

A quick inspection reveled alot of grass, twigs, broken plastic from car accadents, you name it! in front of the radiator. Condensor looked fine (at this time)

I was unable to easily remove the upper air box without "forcing" A/C condensor tubing, so I removed the condensor tubing, and condensor. I held the condensor above my head to see if I could see Day-lite, to my surprise it was heavily blocked with small granules of road dabris.

I had the radiator cleaned and recapped at a local radiator shop, the condensor I cleaned with simple green, and an air nozzle. I Also replaced Opti, Plugs, wires, Water pump, Thermostat, hoses's, and front end air spoiler.

Fired up the car last week for the first time...after cooling system bleeding, and A/C recharge these were my results...

- Outside air temp 90f A/C on (60f) 197-205f Digital Gauge, High fans W/condensor pressure's in excess of 250psi
- Outside air temp 90f A/C off 215-228f Digital gauge, low fans only (cycling)
- Outside air temp 70f A/C on (auto 72f) 195-197 Digital Gauge, low fans (constant)
- Outside air temp 70f A/C off (no data) A/C stuck in auto

Car runs really good..strong & cooler

Sorry about the lengthy post guys, but I'm pretty exited about the results..

 

Few years ago, I tackled cleaning it out. I didn't do that thorough job as desertmike, but close.

I took off the top of the radiator support/cover, stuck a vacuum cleaner hose down and sucked out all the leaves and other crap. I put plastic bag over the fan then took Simple Green and sprayed everything down. Drank a beer. Came back and then blasted the rest of the dirt/grime with the garden hose. After that, the radiator was a champ cooling down the car. Only costed me an afternoon, a beer, and some busted knuckles.

 

On my 95, they are mounted directly to the radiator bottom shroud, left side, three of them. This might be a place to look, are the fans electrical connectors, connected tightly.

CoolVette86, had I taken your advise...I would have spent less money on Beer & Bandades

 

In looking at the car yesterday, I turned the a/c on to see if the fan would come on that way, it didn't. Fan motor out? Also on the motor, is it a single speed, or like a high and low speed?
