New Here And Need A Bit Of Help - Thermostat Housing

[xORIGAMIxARSTSx 0]

Hi

 

I am new here having gently bought a 1990 1.9 GTi

 

I have had a bit of a problem while changing the thermostat as a sheared one of the bolts. I had a mechanic install a helical insert but I am not happy with the robustness of the connection. I have therefore sourced a replacement housing which I will get installed.

 

I plan to get a qualified mechanic to fit the new housing but wondered what the procedure was? any help would be very much appreciated.

 

thanks

Its a very simple job, almost diy for se ody with next to no experience. The only thing id advise is getting somebody capable of setting ignition timing properly.

thanks for your reply. Can I mark the position of the distributor when I dismantle and then simply reassemble?

 

Alternatively I have been quoted 3 hour work from a mechanic to do the whole job, does that sound reasonable?

3 hours seems a tad excessive, an hour should be enough unless you encounter seized/snapped bolts.

 

 

you wont be able to mark the distributor in reference to what its bolted to as it goes through the thermostat housing, which is the part you want to replace, you could mark the distributor in reference to the stud's position in the slot however.

 

 

 

on a standard car removing the airflow meter and bracket will ease access, drain the cooling system, then three coolant hoses, 2 nuts holding the distributor on, one 3 pin electrical plug on a fly lead.

 

unbolt the ignition lead guide but leave the ignition leads attached and move to one side.

 

unbolt the sad, no need to unplug or remove the hoses, just move aside.

 

6x 11mm head bolts and one hidden 6mm allen hex underneath where the distributor bolts on.

 

3 plugs on the rear of the housing for the coolant senders/switches.

 

remove housing, it will be quite stuck in place, clean the head and he new housing, apply RTV sealant or source/make a new gasket (later engines used sealant instead of a gasket)

 

 

re-assemble, bleed coolant, check ignition timing.

 

 

 

 

however if its not leaking at the thermostat takeoff, I'd leave it, it's only under 1 bar of pressure maximum at any time, a helicoil insert will be stronger than the original thread.

thanks for the info.

 

I wanted to change the whole hosing at the helicoil doesn't seem to be well seated. I will take a pic and post it tomorrow as it would be good to hear what you think.

 

there is a small gap to one side of the helicoil which is why I am concerned.

 

I hva esourced a brand new housing.

I think the main issue is the 'Mechanic' they tend to know little about everything and anything and 3 hours for a simple task is 2 hours too much, you only need to half drain the system as the heads higher than a fair bit of it other than that dead simple. Should see half the things I do and what people get charged it eye opening

Job number one should be to visually check your replacement housing is the same as the one coming off, there's more than one type and by now every car is not necessarily fitted with the correct parts for year .
