Re: 1988 camaro rs 2.8 v6 overheating

Have you checked that the fans are running? If you have AC, turning that on should immediately make the fans run. Of course, that doesn't guarantee that the temperature switch is working, the only way to check that is to let it get hot.
Are you losing coolant?

Re: 1988 camaro rs 2.8 v6 overheating

Could be your temp sensor, is it boiling over? are you loosing fluid? What does your temperature control read in the dash? Are you going by the gauge?

Re: 1988 camaro rs 2.8 v6 overheating

Hows the fluid look in the Radiator? Is it boiling in the coolant tank?

Re: 1988 camaro rs 2.8 v6 overheating

I'm not much of a mechanic, I wish I were and could help you more. Sounds like it could be the timing. I know the basics, but get most of my work done by a mechanic.
I know my 2.8 V6 over heated but once I flushed the rad and got a airdam the problem solved. Hope you get it fixed soon. Best wishes.

Re: 1988 camaro rs 2.8 v6 overheating

There is a guy in here that knows these motors inside and out, I will try and find him and add his name to thread. Maybe he could answer some of your questions. His Member name is Maverick H1L, he answers alot of questions about these motors.

I bet you have the wrong directionally water pump and it's spinning the wrong way.

Re: 1988 camaro rs 2.8 v6 overheating

The pulley bolt pattern on those are usually different, plus if you gave them the correct year they should have gotten the right one. Do you know the part #?

Re: 1988 camaro rs 2.8 v6 overheating

Um, Haynes has a nice pic of the water pump on a v-belt car and the pulley still has 4 bolts.

Definitely need to make sure the W/P is designed to go COUNTER-clockwise. I don't have the P/N on the pump I bought a couple years ago (only to find out the belt noise was the tensioner pulley going out) handy to compare. And yes, wrong parts DO come in the right boxes (those were some expensive exhaust clamps I took back to NAPA because some idiot at the warehouse or wherever decided to put 2 1/2" clamps in the 2 1/4" boxes ).

If you're not losing coolant, have an air dam, have a cooler thermostat (stock is 195), and the fan is working, that leaves either clogged ports in the head gaskets, clogged radiator, or backwards water pump. Or a combination of all 3. Try a system flush first, after you make sure they gave you the pump you're supposed to have.

The bolt pattern still has 4 holes but not in the same location.
He most likely has a blown head gasket.

Doubtful... Pump snout looks exactly the same. And he's NOT losing coolant.

Re: 1988 camaro rs 2.8 v6 overheating

If he has the wrong pump, he'd have either an extra bolt hole or a bolt with no place to go. Plus the serp w/p have a cast boss for the p/s pump bracket. Timing cover coolant passages are different too.

Re: 1988 camaro rs 2.8 v6 overheating

ok found the problem it was the thermostat the one in it was made by hypertech 180 with failsafe dont buy them the bore where the thermostat sits in since it had a failsafe it wouldnt allow in to open because the fact the hole wasnt deep enough to let it open up but its fixed now with a 192f thermostat runs like a champ never goes pass 200 now
