ok so headgasket was done on the van last week, done the bottom end shells saturday, fitted a front mount on it yesterday and now overheats and pressurises the water system, she doenst have a thermostat fitted so istn that sticking. has a 12" slimline fan on constant but she gets very hot after 20mins driving especially when on boost.

any ideas??

 

hows the engine sound when running also have ya got all the air out of the system

 

yep bled the system for ages, circulates nice to begin with, engine is quiet when running just needs a new cam as it worn, was fine till the cooler was fitted

 

check the front mounted cooler aint kinking any of the rad hoses, have you still got the water feed on the turbo, as the added capacaty of the cooler might cook the turbo up quicker which may therfor boil the water running through it

 

where are the fans mounted?

on the rad or on the cooler?

You might be now finding that if the fans are on the cooler that you rad isn't coping (not enough air flow) this could also be a sign of a rad thats shot, especially if its not cooling with the rads on constant.

 

regarding the turbo water feed being connected - mine is still connected and I don't have issues with temps rising.

 

fan is on the rad not the cooler, turbo piping is still on and mite be that as my turbo glows loads when under full boost

 

you still got enough air getting to the rad ? and is the fan going the right way ?

 

i was told by ian from powers that if the turbo starts glowing that its a good sign that it could do with a setup.

sure timing along with other things can cause more heat, especilly when driven hard.

also get a stat back in their! never ran one in mine for a while and as their is nothing restricting the flow of water it dosnt cool properly and also causes hot spots.

only going of advice that i was given but i defo helped when i put a stat back in !

hope that helps

Regards John

 

as martins said ive seen it many time where people just turn the fan round and its not letting the engine breathe

 

fan is blowing onto rad so is going the right way, unless the head is fooked i cant think of another reason why as the system is pressurising, when i let the air back out it runs nice and cool again. Maybe time to lose the cvh and join the zetec t crowd

 

mmmm has it got a swirl pot, and how bad was the gasket when it went

 

Did you have the head pressure tested and skimmed when the head gasket was replaced?

 

head gasket was done as my old head was fooked, so had a recon head fitted and standard headgasket. Knowing me ive bought a moody head that is also knackered

 

Why are you hitting full boost when you fitted new shells so recently?

 

run the engine in in 3 days, been building boost up since last weekend, up to 12psi at the moment and thats where its stayin till she gets a new cam and then set up. i did leave the bottle cap half undun and the temp stayed much cooler so the air could escape????
