Hey Steff i found a cure to reduce heat to perfection this bloke told me if you fit this Thermostat ya will thank me it works a treat and ya keep ya heat in heaters see below:
Fan looks great good job i will have a bash for the summer i think but try this stat it cost pennys!!
quinton hazell part no std is QTH117 (88 degree)
QTH104 (82 degree) iff you get the kit the gaskets may be different, think its listed for isuzu trooper 2.2 deisel 9/87-88 ,and ford maveric 2.4 12v 02/93-04/00. iff you compare the stats side by side there iddentical except the opening temp. try it worked for me, hope
stefan:
Tim,
So you put QTH104 in, is that correct? Where did you get one from?
I noticed a slight issue with the fans this morning, if they are running when I go to switch off, the engine runs on for a few seconds after the key is turned off, I reckon the fans must store enough energy to keep the stop solenoid wire live for a few more seconds!!

Yes mate Quinton wont sell it to you but get a Parts Shop to order i tell ya even if i push mine to limit now it does not get above 80Oc!!
PS Forgot you will have to Drill a hole the same size as the litle hole in the Old one as they aint got one in but this took me about a minute..
Its runs lumpy when Cold but as soon as it reaches about 40Oc its fine and ya keep ya heaters ok..

Ive just put an Isuzu 1.7 tdi in my zook, and exactly same problem.
Ive put a damned accurate(1 decimal place) digital temp gauge with the sender in the top hose.
I was gettin a reading of85 ticking over, to 95to 105 when on boost, pulling hard.
Thing is, you could bear your hand on the rad.
I added some more radiator in the form of another cooler plumbed into the heater circuit, and tried again.
This time, just gettin 80 ish when dawdling, and 95 when on hard boost.
Conclusion, its gonna get hot on boost, live with it, try noot to keep hard on the gas for ages.
Also, discovered if I fit a cooling fan to my intercooler, the temp immediately drops about 3 degrees when I switch it on.
