L26 Running Hot


D1RTY6

Recommended Posts

Where'd the motor come from? If it's been sitting for a while half full of water etc they can rust the fins off the water pump.

 

Motor was out of Johns White brougham 260C that i brought, i checked the fins on the water pump when i put the engine in as my last one in my L20 had rusted away, they were all still there and in good condition

Have you flushed abd back flushed the whole thing - it never got hot with john, and its the same rad and engine - also bypass the heater and try that - i know those heater cores can block up pretty bad. Get the radiator out and have it properly cleaned - i know burnside radiators take the tanks off these and do it properly.

A radiator pressure tester / tk head gasket check will give you the good/bad news if the head gasket is blown - these L sixes do have a tendancy to rot the heads and block out when they sit around full of water with no cooland for years aswell.

The funny thing is this car has always done this for you - old engine new engine etc, the only thing thats diff is the heater side and piping. - if your getting the radiator done get the heater core done too.

We checked w/pump also and i helped do the thermostat - id get another one of those.

Sorry i cant be of any actual help but getting someone to do head gasket checks is a first in my book.

Yea it never used to get up to 3/4, just seems to be a progressive thing that's happened maybe 8 months or so ago and hasnt got worse since

 

Yes your right this car does like to test me! like i said earlier will be the 3rd headgasket if it is one... i wouldn't say i thrash it either 

 

Will start with the cheaper things and work my way through what every one has recommended and see how it goes, i just want to be able to drive it up some hills and go on some cuises in it with out worrying about it over heating ha

Flick me a PM man, should be free sunday 

 

Oldschool meet at the Greta Valley Pub on Sunday... you are more than welcome to grab a seat in the diesel ceddy. I also had chronic over heating issues with mine when I got it, a replacement radiator and thermostat had it sorted. The temp gauge doesn't go over 1/2 even after some spirited driving..... I also suspect your radiator

Was considering bringing the Ke36 to this, will have to see what funds are like 

 

 

Yeah my L26 has new everything and sits just below 1/2 in normal operation conditions, FYI.

 

 

Yea as it should, I have had plenty of old shitters and anything that moves over half you should shit your pants and check it out properly.

 

Thanks guys, yea pretty much what i have been doing every time i drive it a fair distance! 

 

Will swap out some pieces and see where i stand :)
