Overheating?

[stephen low]

Sounds like the right sort of plan, then you can be sure and tick those details off as issues if the problem wants to persist.

Curiosity and my uncle finally convinced me too grow a set and pull the heads off to check the head gasket to see if it was backwards (as Rob had suggested the man is never wrong). So as the head came off and I saw the gasket on backwards a huge sigh of relief followed by a loud cheer. Anyway the heads are away being crack tested and checked for warping hopefully all clear on both fronts. I am a bit nervous about getting the rocker right but really shouldn't be that hard as they are the non adjustable variety (gotta love hydraulic lifters) I just hope I have them back in time to have the car running for the club run Sunday.

cheers Andrew

I am sure you all could have heard the cheer on Saturday arvo. Anyway the head are away being crack tested and checked for warping hopefully all clear on both fronts.

Opps just re read the post I forgot the vital piece of information yes the head gasket was backwards, the reason for the loud cheer. Must have been the apprentice engine builder or the friday arvo build after lunch at the pub.

I read through the first page & see you have a couple more pages of suggestions so i'll just be short & sweet.

Make sure you check your timing. bring the #1 piston to TDC & see that the timing mark aligns on your balancer.

Location of your thermostat can make a difference. I have a remote, inline stat that opens in cooler water than is in the block.

Lastly. If your engine is still fresh, it can run a little warmer before it breaks in. Drive accordingly until then.

Well at least the primary culprit has been identified and you didn't do all that work for nothing!!

Should be all plain sailing from here on now Andrew.

Cheers

Well i hope so. That was my biggest fear, was that I pulled the head off and found the gasket wasn't backwards.

If there is a gap there then air will pass through it rather than be sucked through the radiator, therefore decreasing the effect of your thermo fan. You can buy adhesive rubber of varying thicknesses from Clark rubber. This is perfect for sticking in any gaps between your fan and the radiator. These little 5% differences really add up...... Having said that my LS sits around the 200 - 210 mark in racing situations.

Good suggestion. If there is a gap, when sitting in traffic, the fan will pull hot air from the engine bay, through the gap in front of the radiator, and then back through the radiator. Fresh/cool air vs 120+ air makes a big difference. I had an excavator that would over heat...turns out the shroud around the edge of the radiator was bent and allowed the hot air to cycle back through the radiator. Sometimes it is the simplest of things.

Yeah, that would suck. Good to hear you've found and fixed the problem.

Well what a weekend spent all Saturday finishing off re assembling and after 2 goes at tweaking the values I still had a tapping sound. I gave up in disgust and went to the bar. Sunday arvo a mechanic friend offered to come over and have a look fired it up and there was the tapping sound, pull the passenger rocker cover and there was a very loose rocker arm must have had the cam in the right spot when i tighten it up bugger. Checked all the rest all ok, rocker covers back on AGAIN. Fired it up no tapping chattering. You rippa. Just a pity something so simple stopped me making the club run.

Well after a few test runs and driving it too work in the traffic this morning the temp gauge barely moved off 180 F but it was cool morning. So now I just need to wait for a hot day and some traffic for a real test. But suffice to say with the fan coming on at the lights then turning off while moving. I guess the problem is FINALLY sorted if its not be buggered if I know what it is. thanks to everyone for there input and to Rob from the club for his invaluable advice and patience.

Cheers

Andrew,


Great to hear the issue seems to be fixed, nothing worse than a car
that overheats.

This is why club membersship is so valuable, it has saved you time

and more importantly money.
